Ok, I looked in Alternative Fuels section first...
I have 2 fuel tanks with separate gauges, one for primary Diesel engine, one for secondary engine.
I read a 1994 article from New York Times discussing different dyed fuels...
Blue diesel, which is higher in sulfur and tax exempt, is for use in commercial boats, trains or some farm equipment; it is the least expensive. Falling in between is red diesel, which is lower in sulfur than blue, tax free and meant for buses, government vehicles and off-road use.
I don't know what information they were quoting, and I know the difference between OTR and farm diesel... Taxes
That being said... I'm really considering installing a solenoid switched T-valve and running primary engine from whichever tank I want.
Anybody got any feedback? Positive or negative, I don't care. Just looking for previous experiences mostly.
You don't have to commit to which fuel you buy/burn... As you'll notice, I didn't commit to anything either... I spoke true Clintonese
